Suzuki Grand Vitara JB416 / JB420 / JB419. Manual - part 291

4F-12 Electronic Stability Program: 

Step 2: Driving Test
Test the vehicle at 40 km/h for more than a minute including left and right turns and check if any trouble symptom 
(such as ESP

® warning light and/or ABS warning light) exists.

If the malfunction DTC is confirmed at ignition switch ON, proceed to Step 3.
If the malfunction DTC is not confirmed at ignition switch ON, proceed to Step 6.

Step 3: DTC Check
Recheck DTC referring to “DTC Check”.

Step 4: ESP

® Check

According to ESP

® Check for the DTC confirmation in Step 3, locate the cause of the trouble, namely in a sensor, 

switch, wire harness, connector, actuator assembly or other part and repair or replace faulty parts.

Step 5: Brakes Diagnosis
Check the parts or system suspected as a possible cause referring to “Brakes Symptom Diagnosis in Section 4A” and 
based on symptoms appearing on the vehicle (symptom obtained through Steps 1 and 2 and repair or replace faulty 
parts, if any).

Step 6: Intermittent Problem Check
Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.), referring to 
“Intermittent and Poor Connection Inspection in Section 00” and related circuit of trouble code recorded in Step 1 to 3.

Step 7: Final Confirmation Test
Confirm that the problem symptom has gone and the ESP

® is free from any abnormal conditions. If what has been 

repaired is related to the malfunction DTC, clear the DTC once referring to “DTC Clearance” and perform test driving 
and confirm that no DTC is indicated.

ESP

® Warning Light Check

S6JB0A4604002

1) Turn ignition switch ON.
2) Check that ESP

® warning light (1) comes ON for 

about 2 seconds and then goes off.
If any faulty condition is found, advance to “ESP

® 

Warning Light Does Not Come ON at Ignition Switch 
ON” or “ESP

® Warning Light Comes ON Steady”.

ABS Warning Light Check

S6JB0A4604003

Refer to “ABS Warning Light Check in Section 4E”.

EBD Warning Light (Brake Warning Light) 
Check 

S6JB0A4604004

Refer to “EBD Warning Light (Brake Warning Light) 
Check in Section 4E”.

I6JB01460012-01

Electronic Stability Program:  4F-13

DTC Check

S6JB0A4604005

1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector 

(1).

Special tool
(A):  SUZUKI scan tool

3) Turn ignition switch to ON position.
4) Read DTC according to instructions displayed on 

SUZUKI scan tool and print it or write it down. Refer 
to SUZUKI scan tool operator’s manual for further 
details.

NOTE
If SUZUKI scan tool can not communicate 
ESP

® control module, perform “Serial Data 

Link Circuit Check”.

 

5) After completing the check, turn ignition switch off 

and disconnect SUZUKI scan tool from DLC.
